In a random sample of 18 people, the mean commute time to work was 34.8 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean u. What is the margin of error of u? Interpret the results The confidence interval for the population mean u is (Round to one decimal place as needed.) The margin of error of u is (Round to one decimal place as needed) Interpret the results E OA With 98% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval OB. If a large sample of people are taken approximately 98% of them will have commute times between the bounds of the confidence interval OC. It can be said that 98% of people have a commute time between the bounds of the confidence interval OD. With 98% confidence, it can be said that the commute time is between the bounds of the confidence interval
